Expect good resistance to many alcohols, petroleum-based oils, and greases and lubricants. Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.
Maintenance and OEM teams specify it across construction equipment, fluid power, and agricultural equipment.
Stocked as H2.4X16.8 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
